ABSTRACT Cigarette smoking during pregnancy is a significant public health issue that has profound effects on maternal and fetal health. Although many women stop smoking upon pregnancy recognition, a large number continue. Given the higher burden of smoking among low-income women, the focus of this study is to examine the impact of pre-conception social-environmental influences on smoking cessation during the first trimester of pregnancy.
Pregnant women who presented for prenatal were asked to complete a screening form at their first prenatal appointment. Women who agreed to participate were scheduled for a total of four interviews; a prenatal interview at the end of each trimester and a postnatal interview at 2 months of infant age. The sample for the current report consisted of pregnant women (first trimester) with a partner (N=316).
After controlling for pre-conception heaviness of smoking, a number of social-environmental factors were associated with smoking during the first trimester. Women were more likely to smoke during the first trimester if their partner was a smoker; however, the presence of other household smokers was not associated with increased risk for smoking. Additionally, women with a greater proportion of friends (but not relatives) who smoked and more frequent exposure to environmental tobacco were more likely to smoke.
This work found differential impacts of the social network on smoking suggesting that understanding relationship type, not simply number of smokers, may be important for smoking cessation efforts. Understanding differences in social network influences on smoking can help to inform interventions.

    ABSTRACT: to examine whether the severity of different categories of stressful events is associated with continued smoking and alcohol consumption during mid-pregnancy. Also, we explored the explanation of these associations by anxiety and depressive symptoms during pregnancy. Finally, we studied whether the severity of stressful events was associated with the amount of cigarettes and alcohol used by continued users. we conducted a cross-sectional analysis using data from a population-based prospective cohort study. Pregnant women were recruited via midwifery practices throughout The Netherlands. We analyzed women who continued smoking (n = 113) or quit (n = 290), and women who continued alcohol consumption (n = 124) or quit (n = 1403) during pregnancy. Smoking, alcohol consumption, and perceived severity of stressful events were measured at 19 weeks of gestation. The State Trait Anxiety Inventory and the Edinburgh Postnatal Depression Scale were filled out at 14 weeks of gestation. Odds ratios were calculated as association measures and indicated the relative increase for the odds of continuation of smoking and alcohol consumption for the maximum severity score compared to the minimum score. SEVERITY OF THE FOLLOWING STRESSFUL EVENT CATEGORIES WAS ASSOCIATED WITH CONTINUED ALCOHOL CONSUMPTION: 'conflict with loved ones' (OR = 10.4, p<0.01), 'crime related' (OR = 35.7, p<0.05), 'pregnancy-specific' (OR = 13.4, p<0.05), and the total including all events (OR = 17.2, p<0.05). Adjustment for potential confounders (age, parity and educational level) did not notably change the estimates. There was no association of anxiety and depressive symptoms with continued smoking or alcohol consumption. No associations emerged for continued smoking and severity of stressful events. The amount of cigarettes and alcohol consumption among continued users was not associated with severity of stressful events. Our findings may be relevant for health care providers, in particular midwives and general practitioners. The impact of stressful events may be considered when advising pregnant women on smoking and alcohol consumption.

    ABSTRACT: BACKGROUND: The impact of secondhand smoke (SHS) on Southeast Asian children's health has been assessed by a limited number of studies. The purpose of this study was to determine whether in Thailand, pre- and postnatal exposure to SHS is associated with acute lower respiratory conditions in young children. METHODS: We conducted a case control study of 462 children under age five admitted with acute lower respiratory illnesses, including asthma and pneumonia, at a major hospital in Bangkok. We selected 462 comparison controls from the well-child clinic at the hospital and matched them by sex and age. We used a structured questionnaire to collect information about exposure to SHS and other factors. We conducted bivariate and multivariate analyses to identify risk factors for acute lower respiratory conditions. RESULTS: The number of cigarettes smoked at home per day by household members was significantly greater among cases. A greater number of household caregivers of cases held and carried children while smoking as compared to controls (26% versus 7%, p <0.05). Cases were more likely to have been exposed to SHS in the household (adjusted OR = 3.82, 95%CI = 2.47-5.9), and outside (adjusted OR = 2.99, 95%CI = 1.45-6.15). Parental lower educational level and low household income were also associated with respiratory illnesses in Thai children under five. CONCLUSIONS: Thai children who are exposed to SHS are at nearly 4 times greater risk of developing acute lower respiratory conditions. Continued effort is needed in Thailand to eliminate children's exposure to SHS, especially at home.

    ABSTRACT: Pregnancy is a unique period to quit smoking and alcohol consumption and although motivated, not all women succeed at this. We investigated the associations of personality with continued smoking and continued alcohol consumption during early pregnancy. In addition, we studied whether antenatal anxiety and depressive symptoms can explain these associations. Two antenatal measurements from the population-based Pregnancy Anxiety and Depression cohort study were used. Pregnant women in their first trimester were recruited via midwifery practices and hospitals. We analyzed a sample of women who continued (n = 101) or quit smoking (n = 254), and a sample of women who continued (n = 110) or quit alcohol consumption (n = 1230). Measures included questions about smoking, alcohol consumption, the NEO-Five Factor Inventory (personality), the State Trait Anxiety Inventory, and the Edinburgh Postnatal Depression Scale. We found associations between continued alcohol consumption and higher levels of openness to experience, and lower levels of conscientiousness (p < 0.05). The association between conscientiousness and continued alcohol consumption was partly explained by both anxiety and depressive symptoms. No associations between personality and continued smoking emerged. This study contributes to the limited literature on personality differences between women who continue and quit smoking and alcohol consumption during early pregnancy. General population studies have not confirmed the association between openness to experience and alcohol consumption which implies that pregnancy is indeed a unique period. Increased insight in how personality influences continued smoking and alcohol consumption during pregnancy can help health professionals to improve lifestyle interventions targeted at pregnant women.
